Bernard Lazare (15 June 1865 – 1 September 1903) was a Jewish social anarchist, writer, and pro-Jewish activist in France.
Lazare extensively supported the Jewish Dreyfus during the Dreyfus affair.
In 1894, he published Anti-semitism, its History and Causes (L'Antisémitisme, son histoire et ses causes), on the origins of anti-Semitism. It is today considered less politically correct, because Lazare claimed that some Jewish religious and cultural traits were problematic and contributed to anti-Semitism.
